To all whom it may concern:

Be it known that I, CLARENCE W. HOBBS, a citizen of the United States, residingat Worcester, in the county of Worcester and Connnonwealth of Massachusetts, have invented a new and useful Improvement in FlyLeafing Machines, of which the following is a specification accompanied by draws ings, forming a part of the same.

My invention relates to certain improvements in that class of machines which are employed for automatically attaching flyleaves to the inside of cardboard boxes, and particularly to that type of fly-leafing machines adapted to attach fly-leaves taken from a stack or bunch of individual leaves, comprising mechanism for applying gum to the inner side -of the boX and pressing the gummed box against a fly-leaf, with its edge overlapping the gum surface upon the inside of the boX.

The objects of my invention are to provide means for facilitating the application of the box to the machine and positioning the box in registration with the fly-leaf to be applied thereto; to provide means for determining the operation of the pressing mechanism by the presence of a boxin positime to be operated upon; to render the gum mechanism more accessible to the operator;

ment of parts as hereinafter described and pointed out 1n the annexed clanns.

In the accompanying five sheets of drawings, Figure 1 represents a plan view of a fly-leafing machine embodying my invention. Fig. 2 is a side elevation representing that side at the right hand of, the operator. Fig. 3 is a front view. Fig. fl is a side view representing the side at the left of the operator. Fig. 5 is a vertical sectional view on the plane of the broken line 5.5, Fig. 1, showing the operative parts in position for the application of a box to the machine. Fig. 6 is a vertical'sectional viewon the plane'of the broken line 55, Fig. 1, showing the position of the operative parts in the act ofpressing a box against a fly-leaf. Fig. 7 is a detached view'of the fiy-leaf separating device. Fig. 8 is a detached View of the clamp for holding the These objects among others, I accomplish by the construction and arrange,

and gum roll. Fig. 11 is a front elevation I of the ductor roll. j l

Similar reference lette'rs'and figures refer to similar parts in the difierent views. The operative parts. of the machine em'- bodying'my present invention are mounted in a framework comprising the side frames 1 and '2, mounted upon a stand 3, and

united at therear by a cross-bar 4. Sup-- ported upon the sides'l, 2, at the front of the r machine and next the operator is a hori- Zontal shelf 5. Journaled in bearings at the rear end of the machine is a countershaft 6 receiving motion through a belt pulley 7 and imparting rotation througha pinion 8 Specification of Letters Patent. hPatented Feb. 15, 1916.

and gear 9 to a cam shaft 10. The, cam

shaft .10 is connected by means of a sprocket chain 11 with a shortshaft 12 journaled in the side frame 2. The inner end of the shaft 12 has a clutch connection 13, Fig. 10, with a shaft 14 of a gum 'roll 15 which rotates partially immersed in adhesive material contained in a gum box 16. The opposite end of the shaft 14c is counterbored to fit the conical end 17 of a spindle 18 held in the side frame 1, and capable of sliding longitudinally therein, but held in engagement with the shaft 1 1 by'the tension of a spring 19 inserted between a shoulder on the spindle 18 and the end wall of an annular chamber the side frame 1. r

The inner end of'the shaft 12 is provided with a conical tip' 20 which fits a corre sponding counterbore in the end of the gum roll shaft-1 1. The shaft 12 is capable of sliding in its bearing to allow it to be with drawn from the shaft 14L with which it is held in engagement by the tension of a spring 21. For convenience of manipulation the shaft 12 is provided at its outer end with a small knob 22 and the sliding spindle 18 is provided with a similar knob 23.

In its operative position the gum roll 15 is supported upon the conical tips 17 and .20

of. the spindle 18 and shaft 12. Uponthe upper edges of the sides of the gum. box 16 j are formed "two seats 24 and 25 adapted to receive the shaft 14: of the gum roll 15 when "the latter has been released from the conical .tips 17 and 20 and allowed to drop by gravity into the seat/e2 1 3416.25; The seats 24 and are sufficiently close to the shaft 14 when in its operative position to allow the latter to be picked up by the conical tips 17 and 20 through the force of the springs 19 and 21. The sliding spindle 18 and the shaft 12 may be held permanently disengaged from the shaft 14 of the gum roll by any suitable means, such for example, as latches, one of which is shown at 26, Fig. 4, pivoted to the side frame 1 and capable of being dropped between the side frame 1 and the knob 23. The shaft 14 of the gum roll 15 carries a gear 27 which engages a pinion 28 on the shaft 29 of a ductor roll 30, the ratio of the gear 27 and pinion 28 being such. that the peripheral speed of the ductor roll 30 and that of the. gum roll 15 will be the same.

The ductor roll 301s journaled in arms 31,, 31, attached toa rod 32 journaled in brackets 33 supported by the cross-bar 4. Attached to the rod 32 is an arm 34 extending over the cross-bar 4 with its free end resting upon a spiral. spring 35 interposed between. the arm 34 and the cross-bar 4. An adjusting screw 36 passes through a slit in the arm 34 and enters the crossbar 4 for the purpose of adjusting the position of the ductor roll 30 toward or away from the periphery of the gum roll 15, the intervening space between the ductor roll and the gum roll determining the amount of gum which will be carried around the periphery of the gum roll. The shaft 12 carries agear 37 which engages a pinion 38 on the shaft 39 of a' gum transfer roll 40, the ratio of the gear 37 and the pinion 38 being such that the peripheral speed of the transfer roll 40 will be slightly less than the peripheral speed of the gum roll 15, so that when the two rolls run in contact a rubbing action will occur between the peripheries of the transfer roll and the gum roll. The

shaft 39 is journaled in the forked ends of levers 41, 41, pivoted to the inner sides of the side frames 1 and 2.

' The shaft 29 of the ductor roll is held, like the shaft 14 of the gum roll, upon centers 42, 43, as shown in Fig. 11. The center 43 is capable of sliding in the arm 31 for the purpose of releasing the ductor roll with which it ispheld in engagement by means of a spiral spring 44 interposed between a shoulder on the center and the end wall of a recess in the arm 31. A latch 45 pivoted on the arm 31 is employed to hold the center 43 out of engagement with the shaft 29 The ductor roll'may therefore be re leased from its bearings and removed from the machine, and the gum roll 14 may be likewise released and allowed to fall by gravity into the seats 24 and 25 and be supported by them upon the gum box 16.

The gum box 16 is held upon horizontal ways 46, Figs. 5 and 6, allowing the gum box and gum roll supported thereon to be removed together from the rear side of the machine. Capable of sliding vertically in ways 47, Figs. 5 and 6, is a frame 48, connected on opposite sides of the machine by links 49 with levers 50 attached to a rock shaft 51. The rock shaft 51 also carries an arm 5O provided with a cam roll 52 which is held in contact with a cam 53 on the cam shaft 10 by means of a spiral spring 54 by which a properly timed vertical movement is imparted to the frame 48. Ptemovably supportedupon the frame 48 is a gum plate 55 with its lower edge clamped in a groove 56 of the frame 48 by means of clamps 57, 57, Figs. 1 and 8, said clamps being held on a rod 58 carried by the frame 48. The central portion of the gum plate 55 is extended upward, as shown at 55 Fig. 9. The length of the upwardly extended portion 55 is substantially equal to the inside length of the box to which the fly-leaves are to be applied.

When boxes of other lengths are to be treated the gum plate is removed and other gum plates substituted having the upwardly extended port-ion of a suitable length to correspond with the inside length of the-box. The links 49 by which the vertically moving frame 48 is connected to its actuating A levers 50 are provided with cam surfaces 59, one of which is shown in Figs. 5 and 6.

The lower ends of the levers 41 in which the transfer gum roll is carried, are pro vided with cam rolls 60 which are held against the cam surfaces 59 by means of springs 61 connecting the upper ends of the levers 41 with the framework. The action of the cam surfaces 59 is to rock the levers 41 and cause the transfer roll 40 to be swung at the proper time back and forth between the gum roll 15 and the gum plate In Fig. 5 the transfer roll 40 is shown in contact with and in position to receive gum 7,

from the gum roll 15, while in Fig. 6 the transfer roll 40 is represented as swung forward into contact with and in position to impart gum to the gum plate 55, this swinging movement of the transfer roll 40 being accomplished by the vertical movement of f the cam. surfaces 59. Capable of sliding in horizontal ways 62, 62, is a carriage 63 connected on opposite sldes of the machine by links 64 with the swinging levers 65 which 7, extend downward upon the outside of the frames 1 and 2. The carriage 63 comprises two side pieces slidlng on the ways 62 and leaves 78.

connected together by cross-bars72 and 73, the cross-bar 72 carrying a yielding presser bar 74, preferably consisting of an elastic rubber block, having its front vertical face 75 opposing the gum plate'55 when the latt'er'is raised in its highest position, as shown in Fig. 5, with sufficient space between the presser bar 7 1 and gum plate 55 to allow the edge of a box side to be inserted, in the position indicated by the broken lines 76, Fig. 5.

In front of the vertically moving frame 18 and gum plate 55 is a vertically adjustable pocket 77 in which are held the fly- Rigidly supported upon the framework of the machine in front of the upper edges of the fly-leaves 78 is a pressure plate 79 in the horizontal plane of the presser bar 74, said pressure plate 7 9.being adapted to resist the pressure exerted by the presser bar in pressing the box side against the fiy-leaves, as represented in Fig. 6.

The pocket 77 is provided at opposite ends with depending lugs 80 .in which is journaled a shaft 81 carrying a pinion 82 en-- gaging a fixed rack 83 attached to the framework of the machine. The shaft 81 extends through vertical slots 84 in the side frames 1 and 2. Attached to, one end of the shaft 81 is a knob 85 by which the shaft may be rotated by the operator in order to raise and lower the pocket 77 by the rotation of the'pinion 82 along the fixed rack 83. Whenthe pocket 77 has been vertically adjusted it is held in position by tightening a nut 86 onthe opposite screw threaded end 87 of the shaft 81. J ournaled in the lugs 80 is a second shaft 88, to the center of which is attached a radial arm 89 carrying a weight 90. To the ends of the shaft 88 are attached the arms 91, 91, extending upwardly and carrying at their upper ends a cross-bar 92 adapted to bear against the flyleaves, as shown in Figs. 5 and 6.

The bar 92 is held against the fly-leaves by the gravity of the weight 90. The extension 55 of the gum plate is supported on its front side by a series of fingers 93 which are held on the rod 58 and are provided with tail pieces 94: which bear against the'front side of the frame 48. Supported in the side frames 1 and 2 are rods 95 and 96. On the rod 95 are supported a series of fingers 97 Fig. 9, upon each side of the pressure plate 79, and having theirrear faces in alinement with the rear face of the pressure plate.

In Fig. 9 the fingers 97 are shown on one side only of the pressure plate 79, those upon the nearest side in Fig. 9 having been omitted for clearness of illustration. Hinged upon the rod 96 are the bars 98, 98, extending horizontally rearward across theframe 18 and adapted to support the ends of the box as it is applied to the machine. The bars 98 are slidable on the rod 96 to fitboxesof different lengths, and the fingers 93 are slidableupon the rod 58 bywhich gaps 99 may be formed between the fingers 93to receive the horizontal bars 98. The fingers 97 are likewise slidable on the rod 95 to form gaps 100 to receivethe horizontalbars 98.

Hinged upon the rod 32 are thearms 101, 102, connected at theirfront ends by a guide plate 103 having its front surface slightly inclined from aperpendicular to guide the edge of a box placed against'it downward into proper position in front of the .gum .plate 55. The plate 103 is provided with a longitudinal slot 104 for the adjustable attachment of a gage plate 105 provided with a flange 106 resting against the guide plate 103 towhichit is attached by a bolt 107,. The arms ,101, 102,'are provided with cam side pieces of the carriage 63 are provided ,rolls 108, 109, which arev held byfigravity upon the side pieces of the carriage 63. The 8, I

with cam surfaces 110 which 'act to raise the t arms 101, 102, andguide plate 103 as the carriage moves forward. When the carriage is in its rearward position the guide plate 103 is in its lowest-position, as shown in v Figs. 2, 1:, and ,5, but when the carriage is moved forwardthe guide plate 103 will be raised into the position shown inFig. 6. The ways 62 are also hinged upon the rod 32 and .their forward ends arenormally held against the side frames 1 and 2, by means of bolts 111 pivoted .at 112 to the side" frames of the machine and capable of swingingin the forked ends of the horizontal ways 62. Screwed upon the bolts 111 are nuts 113, which may betloosened, allowing the, bolts to be swung free from the forked ends of the horizontal ways 62, allowing the latter to be raised. Detachably held upon the rod 95 by a spring 114 are fingers 115, one

of which is shown in Fig. 7, and sliding in the upper end of the fingers 115, are spin-,

dles 116 having upon their rear ends heads 117 which overlap theedges of the fly-leaves 78 and serve as separators to prevent more than one fly-leaf frombeing removed by its attachment to the g'ummed box.

Journaledi in lugs 118, 118, Fig. 1, pro- 'jecting from the cross-bar 4 is a spindle 119 to which is attached a latch plate 120' which extends forward beneath the presser bar 74: and across the gap between the presser bar 74 and the gum plate 55, with the forward end 121 adjacent to the gum plate slightly raised, as shown in Fig. 5, to bring it in the I path of a box side as the latter is inserted.

between the gum plate 55 and the presser bar 7 1 The'latch plate 120 is'normally held 124C attached to the rear side of the cross-bar 72. The shoulder on the plate 124 engages the latch plate 120 when the carriage 63 is in its rear-most position and holds the car riage from forward movement, except as the latch plate is depressed by the pressure of a box side upon its forward end 121. The pressing mechanism is thereby rendered inoperative unless a box is in position between the presser bar 74 and the gum plate 55.

The operation of my fly-leafing machine is as follows :In the position of the parts shown in Fig. 5 a box is applied in the position indicated by the broken lines 76, the

edgeof the box being'guided by the guide plate 103 and the gage plate 105 into position. As the side of the box resting upon the end 121 of the latch plate 120 is pressed down the latch plate is depressed, thereby releasing the shouldered plate 124 and allowing the carriage bearing the presser plate 7% to move forward and force the side of the box against the gum plate 55 which it is assumed hasalready received a coating of gum by the traversing movement of the transfer roll 40. A. clutch mechanism interposed between the gear 9 and the cam shaft 10 of known construction capable of imparting a complete rotation to the cam shaft and becoming automatically disengaged, is then released by means of a foot treadle 125 operatively connected with said clutch by a lever 126 and link 127, Fig. 1, causing a single revolution to be imparted to the cam shaft 10. The rotation of the cam shaft 10 moves the cam 69 to permit the tension of the springs 70 to carry the presser bar 74 against the gum plate 55. The cam 53 acting against the cam roll 52 rocks the shaft 51 and depresses the frame 18 and gum plate 55, causing the box side in contact with the gum plate to Wipe the gum therefrom. As the gum plate moves downward the cams 59 rock the levers ll toswing the transfer roll into contact with the gum plate, as shown in Fig. 6. When the box has been released from the gum plate the springs 70 continue the forward movement of the presser bar 7 4 carrying the side of the box to which gum has been applied against the rearmost fiyleaf held in the pocket 77. The pressure exerted by the yielding presser bar 74 is received by the pressure plate 79 supplemented on either side by the fingers 97, the ends of the box meanwhile resting upon the horizontal bars 98. The adhesion of the rearmost fly-leaf to the gummed side of the box as the latter is removed will cause the attached fly-leaf to be drawn out from beneath the head 11'? of the separator spindle and also from beneath the cross-bar 92. The completed rotation of the cam shaft 10 restores the parts to the'position shown in Fig. 5 ready for the application of the succeeding box. The latch plate 120 again engages the shouldered plate which holds the presser bar 7 4 against forward movement until the latch plate has been depressed by the insertion of a box. I
